ADSP-2189M
13
The ICE-Port interface consists of the following ADSP-2189M
pins: EBR, EINT, EE, EBG, ECLK, ERESET, ELIN, EMS,
and ELOUT.
These ADSP-2189M pins must be connected only to the EZ-
ICE connector in the target system. These pins have no function
except during emulation, and do not require pull-up or pull-
down resistors. The traces for these signals between the ADSP-
2189M and the connector must be kept as short as possible, no
longer than three inches.
The following pins are also used by the EZ-ICE: BR, BG,
RESET, and GND.
The EZ-ICE uses the EE (emulator enable) signal to take con-
trol of the ADSP-2189M in the target system. This causes the
processor to use its ERESET, EBR, and EBG pins instead of
the RESET, BR, and BG pins. The BG output is three-stated.
These signals do not need to be jumper-isolated in your system.
The EZ-ICE connects to your target system via a ribbon cable
and a 14-pin female plug. The female plug is plugged onto the
14-pin connector (a pin strip header) on the target board.
Target Board Connector for EZ-ICE Probe
The EZ-ICE connector (a standard pin strip header) is shown in
Figure 13. You must add this connector to your target board
design if you intend to use the EZ-ICE. Be sure to allow enough
room in your system to fit the EZ-ICE probe onto the 14-pin
connector.

The 14-pin, 2-row pin strip header is keyed at the Pin 7 loca-
tion—you must remove Pin 7 from the header. The pins must
be 0.025 inch square and at least 0.20 inch in length. Pin spac-
ing should be 0.1 × 0.1 inches. The pin strip header must have
at least 0.15 inch clearance on all sides to accept the EZ-ICE
probe plug.
Pin strip headers are available from vendors such as 3M,
McKenzie, and Samtec.
Target Memory Interface
For your target system to be compatible with the EZ-ICE emu-
lator, it must comply with the memory interface guidelines listed
below.
PM, DM, BM, IOM, and CM
Design your Program Memory (PM), Data Memory (DM),
Byte Memory (BM), I/O Memory (IOM), and Composite
Memory (CM) external interfaces to comply with worst case
device timing requirements and switching characteristics as
specified in this data sheet. The performance of the EZ-ICE
may approach published worst case specification for some memory
access timing requirements and switching characteristics.
Note: If your target does not meet the worst case chip specifica-
tion for memory access parameters, you may not be able to
emulate your circuitry at the desired CLKIN frequency. De-
pending on the severity of the specification violation, you may
have trouble manufacturing your system as DSP components
statistically vary in switching characteristic and timing require-
ments within published limits.
Restriction: All memory strobe signals on the ADSP-2189M
(RD, WR, PMS, DMS, BMS, CMS, and IOMS) used in your
target system must have 10 k pull-up resistors connected when
the EZ-ICE is being used. The pull-up resistors are necessary
because there are no internal pull-ups to guarantee their state
during prolonged three-state conditions resulting from typical
EZ-ICE debugging sessions. These resistors may be removed at
your option when the EZ-ICE is not being used.
Target System Interface Signals
When the EZ-ICE board is installed, the performance on some
system signals change. Design your system to be compatible
with the following system interface signal changes introduced by
the EZ-ICE board:
EZ-ICE emulation introduces an 8 ns propagation delay
between your target circuitry and the DSP on the RESET
signal.
EZ-ICE emulation introduces an 8 ns propagation delay
between your target circuitry and the DSP on the BR signal.
EZ-ICE emulation ignores RESET and BR when single-
stepping.
EZ-ICE emulation ignores RESET and BR when in Emula-
tor Space (DSP halted).
EZ-ICE emulation ignores the state of target BR in certain
modes. As a result, the target system may take control of the
DSP’s external memory bus only if bus grant (BG) is as-
serted by the EZ-ICE board’s DSP.

TIMING PARAMETERS
GENERAL NOTES
Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results for
an individual device, the values given in this data sheet reflect
statistical variations and worst cases. Consequently, you cannot
meaningfully add up parameters to derive longer times.
TIMING NOTES
Switching characteristics specify how the processor changes its
signals. You have no control over this timing—circuitry external
to the processor must be designed for compatibility with these
signal characteristics. Switching characteristics tell you what the
processor will do in a given circumstance. You can also use
switching characteristics to ensure that any timing requirement
of a device connected to the processor (such as memory) is
satisfied.
Timing requirements apply to signals that are controlled by
circuitry external to the processor, such as the data input for a
read operation. Timing requirements guarantee that the proces-
sor operates correctly with other devices.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADSP-2189M features proprietary ESD protection circuitry, permanent damage
may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
